After years of experience I wouldn't use "file" for anything I needed to work reliably.
If the test is really ELF or not ELF, how about detecting the ELF header magic directly? $ if [[ $(dd if="/bin/ls" status=none bs=4 count=1) == $'\x7fELF' ]]; then echo elf ; else echo not-elf; fi elf $ if [[ $(dd if="/etc/passwd" status=none bs=4 count=1) == $'\x7fELF' ]]; then echo elf ; else echo not-elf; fi not-elf Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.
